If the 02 Chevy has a fuse block under the dash take a test light and find an unused spot thatís hot only when the switch is on. Get a spade connector thatís the same size as the fuse spade crimp it to a fuse link. Run your hot wire up through the dash and behind the A column trim panel. While you have trim panels off find a place for the ground wire and make sure to sand or scrape off the paint crimp a ring connector to the ground wire and screw it to prepared area.

Mount your equipment test it out to make sure it turns off and on with the switch, replace trim panels and you should be ready to go.
